Attribution Without a Pixel

Pixel- and cookie-based tracking has been steadily degraded by iOS privacy changes and third-party cookie deprecation. The good news: you can measure what is working without any of it, using first-party data you already own. Here is how.

Three platforms, three answers, one budget to defend. Your GA4 export already holds the answer, and the first finding is free and never leaves your browser. Get your first finding free

Why pixel-based attribution broke

Opt-outs, capped attribution windows, and cookie loss mean pixels now miss and misattribute a large share of conversions. Patching them with modeled conversions inside each platform just re-introduces the platform's bias.

The first-party alternative

Your Shopify orders and GA4 exports are first-party and complete. Causal modeling on that history estimates each channel's incremental contribution without tracking individual users - privacy-safe by construction, and unaffected by the next browser change.

Frequently asked questions

  • Do I need to install anything?
    No - it runs on your existing Shopify + GA4 exports.
  • Is this affected by iOS or cookie changes?
    No - it uses aggregate first-party data, not user-level tracking.
